Technical Specifications Below is a breakdown of the physical and thermal characteristics of this specific part number: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 4.85°C/W (Unducted Flow @ 100 LFM) | | **Dimensions (L x W)** | 30.00mm x 30.00mm | | **Height** | 15.00mm | | **Fin Style** | Fine Pitch (Cross-Cut) | --- ### 2. Design and Component Features #### A. The pushPIN™ Attachment System The "R0" suffix refers to the specific attachment mechanism. This part uses a **spring-loaded pushPIN system**. * **Purpose:** It ensures consistent pressure (clamping force) on the chip, which improves thermal transfer. * **Installation:** It requires pre-drilled holes on the PCB. The pins snap into place, reducing the risk of the heatsink shifting during vibration or shipping. #### B. Cross-Cut Fin Design The fins on the ATS-18H-142-C2-R0 are not long straight bars; they are cut into a grid pattern. * **Omnidirectional Airflow:** This allows air to enter from any direction, making it ideal for compact cases where airflow direction might be unpredictable. * **Increased Surface Area:** The cross-cut increases the total surface area for heat dissipation without increasing the footprint. #### C. Thermal Interface Material (TIM) The "C2" in the part number indicates that the heatsink comes pre-applied with **T766 phase-change material** or a high-performance thermal pad. This eliminates the need for manual thermal paste application during assembly. --- ### 3. Application Use Cases This part is typically found in: 1. **Networking Hardware:** Routers, switches, and gateways. 2. **Embedded Systems:** Industrial PCs and controllers. 3. **Power Supplies:** Cooling MOSFETs or voltage regulators. 4. **Telecommunications:** Base station components. ---
